Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 343,104,013, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 343,104,013 | |
| -1 | -343,104,013 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 343,104,013.
Example:
1 x 343,104,013 = 343,104,013
and
-1 x -343,104,013 = 343,104,013
Notice both answers equal 343,104,013
With that explanation out of the way, let's continue. Next, we take the number 343,104,013 and divide it by 2:
343,104,013 ÷ 2 = 171,552,006.5
If the quotient is a whole number, then 2 and 171,552,006.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 343,104,013 | |
| -1 | -343,104,013 |
Now, we try dividing 343,104,013 by 3:
343,104,013 ÷ 3 = 114,368,004.3333
If the quotient is a whole number, then 3 and 114,368,004.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 343,104,013 | |
| -1 | -343,104,013 |
Let's try dividing by 4:
343,104,013 ÷ 4 = 85,776,003.25
If the quotient is a whole number, then 4 and 85,776,003.25 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 343,104,013 | |
| -1 | 343,104,013 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 193 | 1,351 | 3,281 | 14,939 | 22,967 | 104,573 | 253,963 | 1,777,741 | 2,883,227 | 20,182,589 | 49,014,859 | 343,104,013 |
| -1 | -7 | -17 | -119 | -193 | -1,351 | -3,281 | -14,939 | -22,967 | -104,573 | -253,963 | -1,777,741 | -2,883,227 | -20,182,589 | -49,014,859 | -343,104,013 |
